Specification of Letters Patent.

Application filed May 29, 1916. fierial No. 100,582..

To all whom it may concern:

Be it known that I, BASIL G. AUSTIN, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPneumatic Urgan-Actions, of which the following is a specification.

This invention relates to what I shall for.

convenience term pneumaticorgan action; The title adopted has been asnoted, merely for convenience, although the mechanism is of particularadvantage when incorporated in or forming part of a pipe organ; it isconceivable that {it can be used with equal utility in otherconnections. The action inis situated. v In the drawings accompanyingand forming part of the present specification I have shown oneconvenient form of embodiment of the invention which I will set forthfully 'in the following description. I do not however, restrict myselfto this disclosure; I may depart therefrom in several respects withinthe scope of the invention defined by the claims following saiddescription.

Referring to said drawings:

Figure 1 is a transverse section of pneu-' matic organ action involvingthe invention.

Fig. 2 is an enlarged sectional view of the magnet-operated valve andits ad uncts.

Fig. 3 is an inside face view of the casing for the magnet operatedvalve, and,

Fig. 4 is anoutside face view of the cage for the pneumatically operatedvalve.

Like characters refer to like parts throughout the several views.

The relay mechanismcomprises a main support as 2 and an auxiliarysupport as 3. Both these may as usual be of wood. The main support 2 hascertain windways,-here- 1 inafter described, while the auxiliary support3 constitutes what is known as a relay bar. The two parts 2 and 3 areconnected by parts as 1 having windways as 5; The

part 3 can be held to the part 2, and the connecting tubes 4 canbemaintained in assembled relation with said parts 2 and 3 in somepermanent manner as by screws 6.

The sup ort. or bar 3 carries anumber of cases as generally madeof'm'etal. Adetailed description of one case and its accesseries will,of course, apply to the other, and for this purpose reference may be hadespecially to Figs. 2 and 3. The case therein shown has on its innerside nearthe upper end thereof, the boss 8 adapted to snugly fit thepassage 9, said case having near its lower end also on the irmer sidetheprobar 3. The case 7 is,'therefore, removably mounted. It is held inposition by a spring 12 connected with the relay bar 3 and'bearopen sideof the case 7, fitting a rabbet therein, the packing 1'5 conveniently ofpaper, resting" on the bottom of the rabbet It.will be understood, thatthe thin packing 15 has between its ends a slot 15' in constant registerwith both the ports 18- and 19.

.jection 10 to fit the opening 11 inv the relay I ing against thev capor cover member'13as will. hereinafter more particularly appear;

This cap or cover member 13 closes the outer 7 5 type, the poles of the.magnet being driven into holes inthe said part 13. The free end of thespring 12 to which I have already referred is fitted in an indentation17 in the cover piece or supporting member 13. By

disengaging the spring 12 from said part 13; the latter can bedismounted as can also the? case 7. In the cover piece 13 are ports 18and 19. In the case 7 is an approximately oval flange 20, the space inwhich constitutes a 'port in register with the port 21 of the relay bar3, said port 21 being in commun1-.

similar soft nature. The parts 2 and 3 and their adjuncts hereinbeforedescribed are generally inclosed in a pressure box 2, the result beingthat when the magnet 16 is deenergized, the pressure passing through theports 18 and 19 closes the valve 22 against its seat as shown by fulllines in Fig. 2.

The magnet 16 is normally denergized. I have shown as connected with theterminals of the magnet the wires 25 and 26 con-. stituting part ofcircuit connections which include a battery and a switch or othercircuit-closing device. When the magnet .is

drawn bodily outwardly; so the valve is.

more efiiciently and easily opened.

On the support or relay bar 3 is mounted a pneumatic 27 in communicationwith the port; or passage 9 by way of the port 28. The movable member ofthe pneumatic is connected with the stem 29 of the valve 30 mounted inthe cage 31. This cage consists of a sheet metal shell covering the portor windway 32 leading from a pneumatic (not shown). The valve 30controls the port 33 which it is shown as closing inFig. 1. The cage orelongated shell 31 has in its outer side the, port 34 from which theannular flange 35 extends inward, the inner edge of said flangeconstituting a seat for the valve 30. The

' in communication with atmosphere as is the port 36 into whichthepassage 5 hereinbefore described leads. The chamber 37 in the relaybar 3 with which the passage or windway 5 communicates is also as willbe obvious, in communication with the "atmosphere. The shell 31 ismerely fittedalong the edge of its open side against the support 2;initially it may be held in position by a small quantity of shellacplaced along said edge, although this is not always nec essary, becauseit can be removably held in place merely by the use of the spring 38 (orequivalent means) of bowed form, one end of the spring being seated inthe recess 39 in the upper edge of the relay bar 3, while the other endof the spring fits against the outer closed sideof said cage or oblongshell 31. For holding the cage or shell 31 in proper relation, the pins40 may be provided, these ins extending somewhat freely through perorations in the outer closed side of the cage and being driven into thesupport or windway 33 is port or bar 2. The spring 38 has an eye at itsinner end to fit over the upper of the two pins, by reason of which saidupper pin aids in holding the spring in position. This provides anexceedlngly simple way of holding the cage 31 in place. The use of avalve as 30 and a valve as 22 and the hereinbefore described. adjunctsthereof is in no sense new, the only novelty being in the manner inwhich the cage 31 is mounted,

the Way the spring 38 is associated with said case, and the novelrelation between the I valve22 and its operating'magnet 16 and certain.details as will be more particularly set forth in my claims.

.In Fig. 1 the parts are shown as occupying their normal positions, thevalve 30 being closed against the inner end of the windway or port 33,while the valve 22 is closed against the port 20 as shown by fulllinesin Fig. 2. To obtain the pneumatic action as familiar in organs,the magnet 16 -will be energized to attract its armature '22(constituting a valve) so as to cover the ports 18 'and 19 to pressureand put the pneumatic 27 into communication with the atmosphere. Whenthis condition ensues, the pneumatic or bellows 27 will be collapsed sothat the valve 30 will be drawn away from the port 33' and cover theport 34,

so that the windway 32 will be put into connection with the port 33 byway of the cage 31 to fi'ect the operation of the pneumatic or performsome equivalent act as quite common in or ans.

When t e magnet 16 is denergized the valve 22 is moved by the pressurein the pressure box against its seat on the flange 20 as shown by fulllines in Fig. 2 thus that the packing 15 is free or loose, by-

reason of which it can be readily if desired.

What I claim is:

1. The combination of a support having a port and a windway, a cageinclosing the windway and having a port, a valve in the cage toalternately close said ports, and a spring acting against the cage tohold the replaced :same against said support.

2. The combination of a support having a port and a windway, a cageinclosing the windway and having 'a port, a valve in the cage toalternately close said ports, pins extending freely through the cage anddriven into said support, and a bowed spring bearing against the cage tohold the same against said support, that part of the spring port; thepins and the cage acting jointly to which holds the cage in place,having an guide the valve.
